The present invention relates to novel condensed heterocyclic pyrazolederivatives, to a process for their preparation, to pharmaceuticalcompositions comprising them and to their use as therapeutic agents, inparticular in the treatment of diseases linked to disregulated proteinkinases.

The malfunctioning of protein kinases (PKs) is the hallmark of numerousdiseases. A large share of the oncogenes and proto-oncogenes involved inhuman cancers code for PKs. The enhanced activities of PKs are alsoimplicated in many non-malignant diseases, such as benign prostatehyperplasia, familial adenomatosis, polyposis, neuro-fibromatosis,psoriasis, vascular smooth cell proliferation associated withatherosclerosis, pulmonary fibrosis, arthritis glomerulonephritis andpost-surgical stenosis and restenosis. PKs are also implicated ininflammatory conditions and in the multiplication of viruses andparasites. PKs may also play a major role in the pathogenesis anddevelopment of neurodegenerative disorders.

For a general reference to PKs malfunctioning or disregulation see, forinstance, Current Opinion in Chemical Biology 1999, 3, 459-465.

Accordingly, there is the need in therapy of compounds active inmodulating disregulated protein kinases, and in particular endowed withprotein kinase inhibiting activity.

The inhibiting activity of putative cdk/cyclin inhibitors and thepotency of selected compounds is determined through a method of assaybased on the use of the SPA technology (Amersham Pharmacia Biotech).

After incubation for 60 min at room temperature, thereaction was stopped by addition of 100 μl PBS buffer containing 32 mMEDTA, 500 μM cold ATP, 0.1% Triton X100 and 10 mg/ml streptavidin coatedSPA beads. After 20 min incubation, 110 μL of suspension were withdrawnand transferred into 96-well OPTIPLATEs containing 100 μl of 5M CsCl.After 4 hours, the plates were read for 2 min in a Packard TOP-Countradioactivity reader.

IC50 determination: inhibitors were tested at different concentrationsranging from 0.0015 to 10 μM. Experimental data were analyzed by thecomputer program GraphPad Prizm using the four parameter logisticequation:y=bottom+(top−bottom)/(1+10^((log IC50−x)*slope))where x is the logarithm of the inhibitor concentration, y is theresponse; y starts at bottom and goes to top with a sigmoid shape.Ki Calculation:

Experimental method: Reaction was carried out in buffer (10 mM Tris, pH7.5, 10 mM MgCl₂, 0.2 mg/ml BSA, 7.5 mM DTT) containing 3.7 nM enzyme,histone and ATP (constant ratio of cold/labeled ATP 1/3000). Reactionwas stopped with EDTA and the substrate captured on phosphomembrane(Multiscreen 96 well plates from Millipore). After extensive washing,the multiscreen plates were read on a top counter. Control (time zero)for each ATP and histone concentrations was measured.

Experimental design: Reaction velocities are measured at four ATP,substrate (histone) and inhibitor concentrations. An 80-pointconcentration matrix was designed around the respective ATP andsubstrate Km values, and the inhibitor IC50 values (0.3, 1, 3, 9 foldthe Km or IC50 values). A preliminary time course experiment in theabsence of inhibitor and at the different ATP and substrateconcentrations allows the selection of a single endpoint time (10 min)in the linear range of the reaction for the Ki determination experiment.

Kinetic parameter estimates: Kinetic parameters were estimated bysimultaneous nonlinear least-square regression using [Eq.1] (competitiveinhibitor respect to ATP, random mechanism) using the complete data set(80 points):

$\begin{matrix}{v = \frac{{Vm} \cdot A \cdot B}{{\alpha \cdot {Ka} \cdot {Kb}} + {\alpha \cdot {Ka} \cdot B} + {a \cdot {Kb} \cdot A} + {A \cdot B} + {\alpha \cdot \frac{Ka}{Ki} \cdot I \cdot \left( {{Kb} + \frac{B}{\beta}} \right)}}} & \left\lbrack {{Eq}.\mspace{14mu} 1} \right\rbrack\end{matrix}$where A=[ATP], B=[Substrate], I=[inhibitor], Vm=maximum velocity, Ka,Kb, Ki the dissociation constants of ATP, substrate and inhibitorrespectively. α and β the cooperativity factor between substrate and ATPbinding and substrate and inhibitor binding respectively.

The compounds of the invention can be administered in a variety ofdosage forms, e.g. orally, in the form of tablets, capsules, sugar orfilm coated tablets, liquid solutions or suspensions; rectally in theform of suppositories; parenterally, e.g. intramuscularly, byintravenous and/or intrathecal and/or intraspinal injection or infusion;or by trandermal administration.

In addition, the compounds of the invention can be administered eitheras single agents or, alternatively, in a combination therapy methodcomprising additional anticancer treatments such as radiation therapy orchemotherapy regimen in combination with cytostatic or cytotoxic agents,antibiotic-type agents, alkylating agents, antimetabolite agents,hormonal agents, immunological agents, interferon-type agents,cyclooxygenase inhibitors (e.g. COX-2 inhibitors, in particularcelecoxib, rofecoxib, parecoxib and valdecoxib), metallomatrixproteaseinhibitors, telomerase inhibitors, tyrosine kinase inhibitors,anti-growth factor receptor agents, anti-HER agents, anti-EGFR agents,anti-angiogenesis agents, farnesyl transferase inhibitors, ras-rafsignal transduction pathway inhibitors, cell cycle inhibitors, othercdks inhibitors, tubulin binding agents, topoisomerase I inhibitors,topoisomerase II inhibitors, and the like.

If formulated as a fixed dose, such combination products employ thecompounds of this invention within the dosage range described above andthe other pharmaceutically active agent within the approved dosagerange.

Compounds of formula (I) may be used sequentially with known anticanceragents when a combination formulation is inappropriate.

The invention, therefore, also provides a method for treating a mammal,including humans, suffering from a disease caused by and/or associatedwith an altered (disregulated) protein kinase activity, comprisingadministering to said mammal in need thereof a therapeutically effectiveamount of a bicyclo-pyrazole compound of formula (I), or apharmaceutically acceptable salt thereof, while undergoingsimultaneuous, separate or sequential anticancer treatments.

A further object of the invention is the use of a compound of formula(I), or a pharmaceutically acceptable salt thereof, in the manufactureof a medicament for treating a disease caused by and/or associated withan altered protein kinase activity, in a patient undergoing asimultaneuous, separate or sequential anticancer treatments.

The present invention also includes pharmaceutical compositionscomprising a compound of formula (I) or a pharmaceutically acceptablesalt thereof in association with a pharmaceutically acceptableexcipient, which can be a carrier or a diluent.

The pharmaceutical compositions containing the compounds of theinvention are usually prepared following conventional methods and areadministered in a pharmaceutically suitable form.

Said pharmaceutical preparations may be manufactured inknown manner, for example, by means of mixing, granulating, tabletting,sugar-coating, or film-coating processes.

The liquid dispersions for oral administration may be e.g. syrups,emulsions and suspensions.

The syrups may contain as carrier, for example, saccharose or saccharosewith glycerine and/or mannitol and/or sorbitol.

The suspensions and the emulsions may contain as carrier, for example, anatural gum, agar, sodium alginate, pectin, methylcellulose,carboxymethylcellulose, or polyvinyl alcohol.

The suspension or solutions for intramuscular injections may contain,together with the active compound, a pharmaceutically acceptablecarrier, e.g. sterile water, olive oil, ethyl oleate, glycols, e.g.propylene glycol, and, if desired, a suitable amount of lidocainehydrochloride. The solutions for intravenous injections or infusions maycontain as carrier, for example, sterile water or preferably they may bein the form of sterile, aqueous, isotonic saline solutions or they maycontain as a carrier propylene glycol.

The suppositories may contain together with the active compound apharmaceutically acceptable carrier, e.g. cocoa butter, polyethyleneglycol, a polyoxyethylene sorbitan fatty ester surfactant or lecithin.
